Abstract : The patent relates to an automatic marine navigation system for use with small craft by reference to two fixed points. The fixed points may be moored sonar buoys which transpond acoustic pulses upon actuation by a radio frequency pulse from a remote transmitter on the craft. The time difference between the emitted radio frequency pulse and the received sonar pulse is measured for each buoy, and thence analyzed to obtain a rectangular coordinate plot of the small craft's position relative to the buoys.
